Barney is a chainsaw boss in Boss Pack 6, and yes that's right, the poor guy has built up so many IOU's over the several years, which has resulted in his awful debt to drive him to insanity and as a result, he's gonna solve those IOU's, with a chainsaw. He is stunnable by flashlight so if he becomes a pest use that to your advantage. In a recent Update Barney now marks the player for death on scare for 6 seconds.
